I just know that tomei made an adaptor to put the 70mm Throttle on rwd sr20det but i don't know much about ca18det swap.
I also heard of a stock 68mm Ca18de throttle body from jdm s13.I will check p/n if they are same between ca18det and ca18de.
For any of those i can get almost any part from nissan in japan.

If the bold pattern matches, it would make a nice modification.
On a side note, the KA24E TB requires one to port the intake manifold. I did a crap job when I did it. I need to pull the plenum and have at it with the Dremel again...
